Pulse optimization for multi-qubit gates in transmon system

In transmon qubits, the leading source of errors for quantum gates is the existence of higher energy levels, besides the |0> and |1> states which form the computational subspace. Several methods have been developed to eliminate these errors systematically by clever use of the available experimental controls. In this bachelor thesis we focus on...

A boolean QPQ using single photons

I propose an implementation of the quantum private query protocol as described in an article using a photon to encode a question and reflectionor transmission of the photon as answer options. Each question is represented by a photon in a transmission line with both ends returning to the user, and the answer is represented by reflection or...
